Apple has released Xsan 2.2.1, fixing several bugs in Xsan 2.2. The update is available through Software Update, or as separate installers for Mac OS X 10.6 and Mac OS X 10.5. An updated uninstaller is also available.

This update works only on existing installs of Xsan 2.2. As always, make sure your metadata controllers have OS and Xsan versions at least as great as all your clients. (This is sometimes difficult to control when updates arrive over Software Update. Be sure to manage your clients!) In addition, Apple warns that no Xsan settings should be changed during installation.

The update:

• Improves filesystem reliability
• Improves the cvfsck filesystem repair utility
• Resolves an issue that could cause QuickTime media to report "invalid public movie atom found" on playback
• Eliminates "An unknown disk has been inserted" message when mounting Xsan volumes (occurs in Mac OS X 10.5 Leopard only)
